The definition of the 'animation' shorthand property in
http://dev.w3.org/csswg/css3-animations/#the-animation-shorthand-property-
should (in addition to saying order is important for
animation-duration vs. animation-delay) also mention that
animation-name must be checked last, so that the keyword values for
all of the other properties are not interpreted as an
animation-name.
(It might also be worth reminding implementors that reserializing
the 'animation' shorthand unambiguously may require both (a) putting
'animation-name' last and (b) explicitly giving values for all the
keyword-valued properties, even when they are at their defaults.)
